Class Term

java.lang.Object
  nars.language.Term

All Implemented Interfaces:

java.lang.Cloneable, java.lang.Comparable<Term>

Direct Known Subclasses:

CompoundTerm, Operator, Variable

public class Term
extends java.lang.Object
implements java.lang.Cloneable, java.lang.Comparable<Term>

Term is the basic component of Narsese, and the object of processing in NARS.

A Term may have an associated Concept containing relations with other Terms. It is not linked in the Term, because a Concept may be forgot, while the Term exists.

Field Summary

protected java.lang.String

name A Term is identified uniquely by its name, a sequence of characters in a given alphabet (ASCII or Unicode)

Constructor Summary

protected	Term() Default constructor
	Term(java.lang.String name) Constructor with a given name

Method Summary

java.lang.Object	clone() Make a new Term with the same name.
int	compareTo(Term that) Check the relative order of two Terms.
boolean	equals(java.lang.Object that) Equal terms have identical name, though not necessarily the same reference.
int	getComplexity() The syntactic complexity, for constant automic Term, is 1.
java.lang.String	getConstantName() Default, to be overrided in variable Terms.
java.lang.String	getName() Reporting the name of the current Term.
TemporalValue	getOrder() Get the temporal order in a term, which is null by default
int	hashCode() Produce a hash code for the term
boolean	isConstant() Check whether the current Term can name a Concept.
java.lang.String	toString() The same as getName, used in display.

Field Detail

name

protected java.lang.String name

Constructor Detail

Term

protected Term()

Default constructor

Term

public Term(java.lang.String name)

Constructor with a given name

Parameters:

name - A String as the name of the Term

Method Detail

toString

public final java.lang.String toString()

The same as getName, used in display.

Overrides:

toString in class java.lang.Object

Returns:

The name of the term as a String

getName

public java.lang.String getName()

Reporting the name of the current Term.

Returns:

The name of the term as a String

getConstantName

public java.lang.String getConstantName()

Default, to be overrided in variable Terms.

Returns:

The name of the term as a String

clone

public java.lang.Object clone()

Make a new Term with the same name.

Overrides:

clone in class java.lang.Object

Returns:

The new Term

equals

public boolean equals(java.lang.Object that)

Equal terms have identical name, though not necessarily the same reference.

Overrides:

equals in class java.lang.Object

Parameters:

that - The Term to be compared with the current Term

Returns:

Whether the two Terms are equal

hashCode

public int hashCode()

Produce a hash code for the term

Overrides:

hashCode in class java.lang.Object

Returns:

An integer hash code

getComplexity

public int getComplexity()

The syntactic complexity, for constant automic Term, is 1.

Returns:

The conplexity of the term, an integer

compareTo

public final int compareTo(Term that)

Check the relative order of two Terms.

based on the constant part first

Specified by:

compareTo in interface java.lang.Comparable<Term>

Parameters:

that - The Term to be compared with the current Term

Returns:

The same as compareTo as defined on Strings when the constant parts are compared

isConstant

public boolean isConstant()

Check whether the current Term can name a Concept.

Returns:

A Term is constant by default

getOrder

public TemporalValue getOrder()

Get the temporal order in a term, which is null by default

Returns:

The default temporal order
